合成路线1
该中间体在本合成路线中的序号:(XV)Treatment of (R)-1-chloro-2,3-propanediol (I) with either K2CO3 or Cs2CO3 in CH2Cl2, followed by O-protection with Trt-Cl and Et3N in CH2Cl2, yields (S)-trityl glycidol (II). Alternatively, derivative (II) can also be obtained either by direct O-protection of (R)-glycidol (III) by means of Trt-Cl and Et3N in refluxing CH2Cl2 or by cyclization of protected propanediol derivative (IV)--obtained from treatment of compound (I) with Trt-Cl and Et3N in CH2Cl2--by means of KOH in EtOH. Reaction of (S)-trityl glycidol (II) with vinyl magnesium bromide (V) by means of CuI in THF provides (S)-1-(triphenylmethoxy)-4-penten-2-ol (VI), which is then condensed with allyl bromide (VII) with KOtBu or NaH in THF to afford compound (VIII). Ozonolysis of (VIII) in CH2Cl2/MeOH, followed by reductive quench with NaBH4 in NaOH, gives (S)-3-(2-hydroxyethoxy)-4-(triphenylmethoxy)-1-butanol (IX), which is then treated with MsCl/Et3N in CH2Cl2 to yield bismesylate (X). Coupling of compound (X) with 2,3-bis(1H-indol-3-yl)-N-methylmaleimide (XI) [obtained by treatment of dichloromaleic anhydride (XII) with methylamine hydrochloride by means of NaOMe in HOAc to furnish dichloro-N-methylmaleimide (XIII), followed by Grignard reaction of (XIII) with indole (XIV) in toluene/THF by means of EtMgBr in Et2O] by means of Cs2CO3 in DMF gives the 14-membered macrocycle (XV).

合成路线3
该中间体在本合成路线中的序号:(XV)Hydrolysis of macrocycle (XV) with KOH in refluxing EtOH yields anhydride (XXIII), which is then treated with hexamethyldisilazane (HMDS) and MeOH (in DMF at 80 C) to afford compound (XXIV). Detritylation of (XXIV) with either HCl in CH2Cl2 or HCl in refluxing EtOH gives alcohol (XXV), which is treated with methanesulfonic anhydride and pyridine in either refluxing THF to produce mesylate (XXVI). Finally, the desired product is obtained by reaction of (XXVI) with dimethylamine in THF or DMF. Alternatively, the conversion of (XXV) into the target compound can also be performed by following these steps: treatment of (XXV) with bromine, pyridine and triphenyl phosphite followed by reaction with pyrrolodione provides bromo derivative (XXVII), which is finally converted into the target compound by reaction with dimethylamine in DMF.

合成路线4
该中间体在本合成路线中的序号:(XII)Protection of (R)-glycidol (I) with trityl chloride (II) and TEA in dichloromethane gives the trityl ether (III), which is condensed with vinylmagnesium bromide (IV) in THF to yield the pentenol (V). The alkylation of (V) with allyl bromide (VI) by means of NaH in THF affords the allyl ether (VII), which is oxidized with O3 in methanol/dichloromethane, giving dialdehyde (VIII). Reduction of (VIII) with NaBH4 in ethanol provides diol (IX), which is treated with mesyl chloride and TEA in dichloromethane to afford the fully protected alcohol (X). Cyclization of (X) with 3,4-bis(3-indolyl)-1-methyl-2,5-dihydro-1H-pyrrole-2,5-dione (XI) by means of Cs2CO3 in DMF yields the hexacyclic compound (XII), which is N-demethylated by reaction with KOH in refluxing ethanol to give the hexacyclic furan derivative (XIII), which is then treated with hexamethyldisilazane (HMDS) in hot methanol to afford the hexacyclic demethylated pyrrole (XIV). Elimination of the trityl protecting group of (XIV) with HCl in dichloromethane gives the methanol derivative (XV), which is treated with Br2, pyridine and triphenyl phosphite in dichloromethane to yield the bromomethyl derivative (XVI). Finally, this compound is treated with dimethylamine in DMF to provide LY-333531. Alternatively, compound (XV) is treated with methanesulfonic anhydride and pyridine in THF, giving the mesylate (XVII), which is then treated with dimethylamine as before.
